What Is DIMM?

by Nichelle Coleman

A DIMM or dual in-line memory module resides on a computer's motherboard. The module helps the computer process memory and data. The DIMM memory module is preferred over SIMM or single in-line memory modules because it operates at faster speeds. One DIMM module can do the job of two SIMM modules. The DIMM comes already installed on a PC but can easily be replaced by a user.


A DIMM memory module has a 168-pin connector and can transfer data at a rate of 64 bits. This is a faster rate compared to SIMM memory modules that operate at speeds of 32 bits. Users prefer the faster pace of a DIMM.


DIMM memory modules allow multiple lines of communication within a computer. DIMM connectors link up to different circuits as opposed to a SIMM, which can only produce a single line of communication.


A DIMM is the preferred option if a system processes large amounts of data. Most businesses rely on DIMM modules because of their efficiency. DIMM can also provide reliability for users who are connected to a home network. The DIMM module allows the computers on a network to transfer data at a reliable rate of speed.


The DIMM module assists a computer in processing memory. The DIMM connects with the data bus of the computer as it is attached to the mother board. A DIMM can detect data errors, and some DIMMS are known as error correction code (ECC)-enabled DIMMs. These types of DIMMs are normally used in servers. The chips on the DIMM checks for errors and attempts to fix them. Most computer motherboards for home use are not designed for these type of DIMMS.


A DIMM is installed on a computer's motherboard by placing it into a slot. The DIMM is offered in several sizes and is simple to replace as needed. To replace the DIMM, the user must simply open the casing of the PC and remove the DIMM from its slot. It is best to wear an antistatic wrist strap so that damage is not caused to the PC. If replacing a DIMM, once it is inserted and the computer is rebooted, the system will automatically recognize the DIMM.
